We normally book vessels a minimum of two weeks in advance... but do please ask if you want a short-notice charter, we will try to accomodate you! In order to get your preferred dates and vessels, though, we advise getting in a lot earlier ... demand is already strong for the 2019-20 season!
We contract with our vessels in May each year for the following summer. For this reason we don't confirm bookings prior to the end of May each year for the following season, (in case the fleet mix changes.) However, we we do record booking requests further in advance so people can get their names down and have first refusal once the vessels are set.
